Chipflasher’s Road towards RYF...

Dear Folks! Zerocat’s Chipflasher has been certified! First ten devices – tagged with the Free Software Foundation’s “Respects-Your-Freedom” (RYF) Certificate – are now available as a Limited Edition. Read the Full Story. See our Shop and help to further fund the project with your purchase!


Zerocat is run by Kai Mertens. Friends and contributors are Hoki, Tomás and Ricardo, as well as some pioneer customers and supporters. We are running a small mailing list and we use PGP-encryption with GnuPG.

For any question or feedback, feel free to get in touch. Our PGP-key is available for download from this site, see PGP-Key.

If you need to see a tool or hardware which does not yet exist as free-design, we would love to hear about it!

Please also be aware of networks like These will be of interest to you if you are looking for a vision of free-software business practices.

To sum up: If you want to do things differently, there are ways to do it! Spread the word, tell people about it and engage a free-design hardware hacker! We will all win ;-)
